` 2 'sHBBTs-sHEBT` z *UNITED srnrns' i ,EDMUND H. LUNKEN AND CHARLES M. CO'NKLIN, OF GIi\'CIN.N.\TI, OHIO, ASSIGNORS, BY

DIRECT AND. MESNE ASSIGNMENTS, TO THE LUNKEN STEEL WINDOW CO., A CORPO- RATION OF OHIO.

Be it known that we, EDMUND H. LUNKEN and Ci-iARLns M, CoNKLiN, citizens of the United States, residing at Cincinnati, Ohio,

have invented certain new and useful Iniproveinents in Metallic Window Construction, of which the'l'ollowing is a specilication'.

Our invention isan vimprovement in inetallicand mineral composition windows of the general class disclosed in au application for Letters Patent ol the United States liled by us October 30,1906.

' Our present improvements relate, in the main', to spacing means between the inner and outer members, ol which the vglass carry ing frame is composed; to means for reinforcingi lie glass holding means at the point- Ofjuncture between the said holding means and the'glass; to an arrangement of muntin and Aframe members whereby protection from the actio'nloll heat is ai-lorded and'thc parts are strengthened to resist distortion:

' and to features ol' construction and combination and arrangement of parts hereinafter .described and particularly pointed 'out in the claims.

The invention is illustrated in the aecompanying drawings' in which Figure 1 is a perspective View of a window embodying our invention. Fig. 2 is a detail sectional view onthe line 2-2 o'l Fig. 1, with the swinging frame closed. Fig. 3 is a seetional` view on the line 3-3 ot Fig. 1, and

Fig.'` 45 is a detail sectional view on the line4 0f iFlg. il.7

Figs. 5 and 6 are detail views of the spacing members.

Referring to Figs. 1 and 2, the mainframe of the window is shown at 5 and the glass carrying frame at 6.'v This glass carrying frame is pivoted to the main frame at 7 in a f manner similar to that disclosed in the apinner and outer members is the spacing and.

lieation referred to. The swinging rame, likefthat shown and described in said application,` is composed mainly of three parts, the outer pressed steel or mineral. composition member having a flange 8 and the rim 9, 4the innerinember composed of flat bars 10 forni? inga rectangular frame and between these glass holding means. In our present construction this spacing means comprises the channel member 1l formed of fire proof ina terial, said member fitting between the inner Specification of Iietters Patent.

y and outer members Where it is held by the rivets or bolts 13 arranged near opposite edges ol' the said member and' l relation.

I tially O shape in cross sections, 4having its open or channel side directed towards the outside of the window with its edges resting upon the lining 30 ol asbestos or other 1101iconducting material. '.lhe, limbs the U shaped member provide .transversely extending parts at di'll'erentdistances from the edges ol' said l'ramc members. A dead air space-is' provided 'by this construction at 12. The important features and advantages ol" this construction and arrangement of the spacing member will be referred to more at description oll the muntins at which a si inilar spacing vmember is employed and in substantially the same relation.

y le have extended the stop strip 15 `oi the swinging l'rn me to make it reach over that portipu oi' the inside member 10 ol`- the swinging frame which furnishes the means for holding the putty and glassfand this overlying part of the stop strip extension is pressed o r rolled into a bead or channeled portion 16, It thus rovides a strong reinforcement or backing or the edge ofthe glass and will sustain the edge ol" the glass against lateral pressure and thus resist the force of a stream of water turned upon it from-a hose to a'sulllieient degree to ineet the'fire-underwriters requirements. This rolled oi pressed edge of the stop oi' reinforcing strip will present an ornamental appearance at the inte` rior 'face ot' the swinging 'fi-ame.

Referring to Fig. 3, we illustrate here the upper portion of the lower stationary panel or rame 1'7 and the lower portion of the upper swinging frame 6. It will be observed swinging frame is provided like that above described with ya reinforcing or channeled portion 16 to sustain the inner plate or .inemer 10 of the swinging frame against force applied to the outside of the' window, andl particularly to force'applied to the glass. The stationarypanel 17 isv composed ofthe 'inner and outer frame members 10 and 9 with the removable bar 18 securedbetween the u per edges thereof by means of the bolt 19 an nut 20; thispart being removable so that the length hereinafter in connection with the that the stop strip on the lower portion ofthe glass shown at 2l may` be yremoved and reso as to provide a rim 24 extending outwardly some distance, the said rim being triangular in cross section and Abeing hollow and having its flang`e 25 fitting against the outer face of the outer rim member 9 where it is secured by bolts 19. These hollow7 rims 23-24 roi vide dead air'spaces which like the dead air space 12 prevent conduction of' heat. The

hollow rim 24 presents an inclined upper side' to shedthe water and direct it outwardly from 9X, which in the Window and the swinging frame at its lower edge is provided with a continuation of the outer plate or member 9, as shown at to direct the-water from the window.

Referring now`to Fig. 4, which shows the constructionof themuntins, it will be seen that we employ an outside member 26 consisting of a at bar'or sheet 'of metal and an 'inner member consisting of a sheet or bar of metal 27, the `edges of which are bentv to form the hollow angular beads or. rims 28; which serve to stilfen the muntin on the inner side and provide dead air s aces' at these oints. The inner and outer'p ates or mem` bers 26-27 are spaced apart and are connected by the channel members 28 and the stag; ered bolts or rivets 29. The channel mem.- er 28X iso U shape in cross section and its edges rest u on the lining 30 of non-conducting materia such as asbestos. This spacinor member' 2S rovides a dead air spaceand the asbestos. g prevents the conduction of heat'to this space;v and also prevents the conduction of'heat between the members 26 and 27. The glass -is shown at 31 extendin with its edges etween the' members-26 an( 27.' The rivets or bolts 29 pass through openings in the member 26 of slightly larger diameter than the rivets. This W allow the plate or member 26 to expand in all directions without affecting the connecting rivets. The plate or member 26 serves as .a protection'to the partsl ofthe muntin on the inner side thereof and this plate under the action of heat will buckle or become distorted only to a minimum extent, because of the fact that it is formed plain throughout and is free from ribs or projections. The stiffer a metal plate is when'cold the greater its `tendency is to.

buckleunder the action of heat, and therefore this -plate 26 is made'plain sothat while affording an efficient means of holding in the glass, it will not buckle to such an extent as to Adisrupt thejoints and-,expose the inner parts. The" protection afforded by this plate will enablethe inner part-'s to remain, comparatively cool, and they being stiened by ming downwardly also servesv sv neas the channel form and the beads or rims will A maintain the structure in its original shape. lt will be noticed that the channel of the member 28X is directed outwardly. This is of special importance as the amount of sur-l face in contact with the outer portion of the member at its main portion o r bottom is p' directed outwardly and wardly.

As above stated, the spacing member 11 of the swinging fra-me presents the same advan- 1ts channel facingintages at said frame as do the spacing members o' the muntins, that is provides a dead air space; it has a limited bearing at its edges l against the outer frame member; it bears on the asbestos, vand its general arrangement.
